Studio 7 error generating db scripts

Support
#1

Hi,

I got studio 7.1.1 following error whene generating db scripts.

The project compiles correctly and application runs without complaining of anything. I have try to clean then reassemble, everything ok, but same error happens when generating db scripts.

It seems there is an issue on a column but the error does not mention column name, that would have been helpful.

Regards
Michael

Hi, @michael.renaud!
We will add a more detailed description of the errors.
Can you see all the enumerations that are used as attributes of an entity? Are there among them those that are not inherited from com.haulmont.chile.core.datatypes.impl.EnumClass?

Hi @zlatoverov

You got it. I had the following class below of which some of my enums were inherited.

public interface LocEnumClass<T> extends EnumClass<T>  {
    default String getCaption() {
        return AppBeans.get(Messages.class).getMessage((Enum)this);
    }
}

I changed it this way.

public interface EnumLocCaption  {
    default String getCaption() {
        return AppBeans.get(Messages.class).getMessage((Enum)this);
    }
}

Not replacing EnumClass but as a complementary interface.

public enum CarEntryState implements EnumClass<Integer>, EnumLocCaption {

Error disappeared.

Thanks
Michael
